ac compressor clutch hub falls of onto street

yep, if you look at the last sentence in my 1st post, I did mention "and be prepared for locking spring inside too." I totally forgot what the technical term for it is though. snap ring. reason I asked is you are now driving with a pulley that stays there on its honest word.
here's a practical suggestion. find out is 2001 was produced without a/c. if yes, your luck, and buy belt for no a/c option engine. as a result, you are not taking chances of pulley coming off, along with belt. if you have separate a/c belt - amen, simply take it off.
keep in mind, your a/c wants to turn on every time you have blower set to defrost/defog. you prolly also want to disconnect a/c harness plug too.

You cant just buy a used outer friction plate and replace the missing bolt, just to see if it engages and runs ok?

note; small shims go under the friction plate to make correct gap for clutch/plate clearance

Right. Now, you said "you CANT just buy........", you meant, I feel, "you CAN just buy......" and try it, right? Thats what Im hoping to locate- just the friction outer plate/shims/9mm nut.

Thanks, UK. Man, youre working too on Thanksgiving....LOL!! Well, Im sure glad. hey, that link may be a good choice if I fail to locate a used plate/shims/nut. But, geez, I just cant see how a pulley held by snap ring can "wiggle' off. Guess theres always the chance. Now, its not so easy you know, to remove a serpentine from a TIGHT civic. Those cars are murder to work on. But, I will call AZ to see if they do stock such a belt, for the heck of it.

hah, am actually driving to see a patient next. will be half day project.
snap rings are not walls. you have very little contact surface to hold anything in place. just my 2 cents. and a lot of tension on pulley.
does it have separate a/c belt? guess not, if you calling AZ.
yes, Japanese cars are made for masochists with tiny hands. but if you figure out how to do it initially, they are very easy to do over.
do you have comp access from the bottom, through tire well? that's a life saver in many cases.

First off, 01' Civic's have three belts (minus timing belt), one alt, one p.s., and one a/c, so just remove that a/c belt if you need to. The snap ring does all the holding for the pulley, losing the outer plate will have no effect. The outer friction plate bolts onto the center hub with that little bolt, the center hub turns the compressor when activated, and free spins when not. So the pulley has to spin at all times, which means it is fixed to the outer body of the compressor. Also the inside of the pulley has a bearing which is tightly fit to the hub (how all bearings work) and that is where all the pressure is, on the bearing. There isn't much if any pressure to pull the pulley out away from the compressor, the snap rings holds it just fine.

As long as the bearing is good you can run it as is with no worries until you can afford to fix it right. It is basically just an idler pulley now with the clutch plate off. I have removed the clutch plate for a few customers who's compressors seized so they could save up to repair properly.

More good tips- and encouragement. UK, AZ is closed today. for the record.

But, with the tip from D, yes, there are seperate belts down there (I actually remember working down there 2 yrs ago when putting on these belts!). But, since DG offered the assurance it wont fall off, I'll keep it there for the time being (which wont be more than say, a month).

So, D, maybe your explanation will sink in my head easier- when the coil is activated/charged with current, is it the outer plate that moves toward the comp or the inner moving toward the outer plate? Cuz, isnt the outer plate bolted on tight to the shaft that is rock solid stationary since its basically the crank shaft?

D-Rock, you are IT now.

NQ, it's your call. there was some, LIKELY NOT GOOD reason, that plate fell off. personally, I have never ever heard of that "just happening". you want to rely on snap ring and bearing - fine. belt costs about 10 bucks, and takes about a minute to cut it off, if you don't want to mess with removal. if that pulley comes off, and belt flies in between the other 2 belts, and it's prolly the one BEHIND them anyway, not gonna be 10 bucks in repairs.

exactly. bolted onto the shaft. so something slides somewhere, right? even just a bit.. say, like brake pads.

OK, UK, I know youre just looking out for me, and no sarcasm/joke- but I know you well enough youre advising the best you can, and really care. Now, I am scared (lol). OK, as soon as I can, its AZ for a belt (maybe tomorrow, gotta kill time somehow). Who needs a biger mess than what Ive got now.

(going to a buddy to eat turkey now- kinda late, but still should taste good)

Finally got a used comp that I was hoping to scavenge the clutch plate/nut. BUT, tonight, I tried it and dang- apparently, the splined end of the shaft has been kinda damaged/chewed up from weeks of it jiggling around until it finally fell of on the road. Oh well- just as well cuz the clutch bearing is also "bent" where you can see the balls inside even!!

So, gonna remove compressor, and install new one from junk yard. Its a chance, I know. So, what can one do on a bench with a junk yard comp to check it out? Its a scroll comp. With a thermal protector (is that the same as a diode?). Can I at least verify the wiring to the magnet works by connecting it to a 12v battery, and activating it? Should one "see" the clutch move toward the outer plate, people? Also, I will brake clean the innards then also, need to add proper amt of oil.

ac compressor clutch hub falls of onto street

Thanks man. Better safe than sorry. **** flying all over engine compartment is no good to encounter.
I jumped 12V on a/c comps before, never really had any trouble, and did it on on a car and with engine running.
it should go from free spin to lock. if you are benching it, you should feel it from hand. you may not see it. free spin - lock. I don't think you'll be able to turn compressor by hand, ha-ha.
as of t. protection - know nothing.
we de-seized several compressors back in times, so one thing I know for sure - before you turn it, you oil it. or it'll seize in about 10 seconds. you can hand crank it with socket wrench via center bolt, I am not aware of them being directional. so you crank and add oil, crank and add oil.. it slowly sucks it in and lubes itself.
oh man.. now you have to purge the system, vacuum it, and refill... and it has to be just the right weight added, or it will not work.. have fun and god speed.

ac compressor clutch hub falls of onto street

Dont worry, UK, I now al aout weight/vac, etc etc etc . Just stuck on this coil now, maybe have to pull off pulley/reinstall onto other comp with a press. Fuuuuuun!

OK, so I put on 12v and got just a wimpy quiet click- the entire circumference of the plate did nOT mate nicely to the pulley face end. Then, I tested for ohms at the red/blk wires about 2-3" from actual coil, and got infinity!! Indicates bad coil, unless I wa supposed to probe right AT the coil itself(?)

ac compressor clutch hub falls of onto street

swap out coils?
take clutch plate off one you just bought and try it out on the OEM one and see how it behaves? You can install plate back well enough to try that, right? not saying permanent install.
That's me. Otherwise, I am very dumm electrically, only basic stuff.
I'll pm you with something.
